The present invention relates to a stone sculpture processing method, and as a certain point of a stone sculpture made of granite is polished by a specific method, the corresponding point changes to a unique color, and a stone sculpture processing method that allows the stone sculpture to produce a more excellent aesthetic Its purpose is to provide. To this end, the stone sculpture processing method according to the present invention, the process in which a certain point of the stone sculpture cut into a predetermined shape is changed to a specific color is specified through a GC cup grinding stone mounted on a grinder that provides a rotational force of a certain speed. A basic surface treatment step of polishing a corresponding cutting surface for a change in color for a predetermined period of time so that the irregular surface is smoothly treated; The point where the basic surface treatment is completed is repeatedly polished several times for a certain period of time through a PVA grinding stone mounted on a grinder that provides a rotational force of a certain speed, and the corresponding point is surface-treated more smoothly and the gloss and color peculiar to the stone A main surface treatment step to show and; The point where the main surface treatment is completed is polished for a predetermined period of time through a metal brush mounted on a grinder that provides a rotational force at a constant speed, and the fine particles of the brush penetrate and absorb into the polishing point of the stone, resulting in a unique color. It consists of the process of changing the surface color to make the
